    Hello everyone. I need some help.
    I have two layers. If I rotate LayerA, I want LayerB to rotate at the same angle.
    If I rotate layerB. I want LayerA to rotate at the same angle.
    Is it possible using expressions?

    That’s a creative solution!
    The problem is that it’s part of a more complex composition. I have some layers linked to these two A and B. In fact, there will be more than 2 layers controlling each other. I am trying to get a kick start. I’m not sure if I explained it properly. My English only goes so far.

    I just realized I’ll have more issues if I go this way. Figuring out which layer to control with keyframes, for example, seems complicated. I think it’s better to use a slider that controls all the involved layers. Thank you for the help!

    simplicity is best in AFX expressions!

    I was going to suggest the same thing. Just use a slider expression controller and link the rotation of any layers you want to rotate to the value of the slider. This is pretty simple to do, even if you don’t know how to write expressions from scratch with javascript.
